The three day (72-hours) PCR testing will no longer be applicable for residents travelling from a High-risk country. Take note that if a traveler is traveling via a High-risk country as a non-transit passenger, meaning staying in the respective country for more than 24 hours, the requirement of two-day testing prior to departure shall be applicable. Transit passengers, those staying less than 24 hours, from non-High-risk countries can continue to test three days prior to departure date.
